and I'll post the answer tomorrow unless someone guesses it before then.
Here's the background. I'm in the state of Maine, USA. My company needed
another truck for odds and ends, so last month we bought a used 1994 Ford
F150 4X4 with 69,000 miles on it. The truck had been in an accident, but
was all redone and repainted. It looks great inside and out. On our test
drive it went great. It doesn't get a lot of use. Also remember its cold in
Maine this time of year. I took it out one cold morning after it had sat for
a couple days. At about 40 mph the steering wheel shook ***ly. I
thought the left, front wheel was coming off. I stopped and checked it out,
but all was well. After a few miles the shaking was less, and eventually
went away almost completely even at 60 mph. The tires are Goodrich steel
belted radials with no cupping or other signs of uneven wear. The next
morning I took it out again, and it shook again, but not so badly and it
went away sooner. The truck sat for a couple days without use. 2 mornings
later I took it out again, and sure enough I thought the wheel was gonna
fall off. *** shaking. But again, after10 miles or so the shaking
lessened and eventually stopped.
We checked the tires in the morning for flat spots (not likely on steel
belted radials) and there were none. The conclusion was that the truck does
this only when it's real cold and comes out of it when it warms up. Usually
its worse when it sits for 2 days than if it just sits for one day. If it
sits for a day, but you don't take it out until after 1 or 2 PM, its not bad
at all. It always comes out of the problem after being run for a few miles.
Sitting for more than 2 days doesn't make it worse than just sitting for 2
days.
Okay gents. What do you think was wrong with it?
